240 CHEILANTHES AND MAIDENHAIR. 
and three times pinnate. It is also of more southern 
distribution, extending to Mexico and the 
West Indies and barely reaching Virginia and 
Missouri on the north. Like most of its rela- 
tives it loves dry and exposed situations and is 
often found in places where it does not receive 
a drop of water for weeks or even months. 
The fronds are rather long and narrow, and 
dull green in colour. The primary and second- 
ary pinne vary from ovate to lanceolate and 
are usually broadest at base. The ultimate 
pinnules are very small and roundish in out- 
line like little green beads. The terminal seg- 
ments are about twice as large as the others. 
The stipe is chestnut-brown but the colour is 
hidden under the dense coat of hairs. The 
sori are marginal and arranged in such a way 
as to appear to form a continuous line on the 
edges of each pinnule. In youth the edges are 
flattened over them ina pale green indusium, 
but later they push from under it and may be 
seen dividing the margin from the tuft of to- 
mentum in the centre of each pinnule. From 
its coat of tomentum, this species is some- 
times called, in the books, the woolly lip-fern. 
Cheilanthes Lanuginosa. 
This species is likely to impress the observer 
as possibly a diminutive hybrid between C. 
vestita and C. tomentosa. The cutting of the 
fronds is similar to that of west7ta while the 
woolly covering of the under surface is like that of /o- 
Chetlunuthes tomentosa.
